Abstract:
    This invention discloses one spot measurement carve stress test method and device for channel stress test, which uses one same rock core and stress for stress elimination measurement and stress restore device, wherein, the rock wall stress test device comprises upper and down saddle pressure blocks to form round hole size and its load rock chip diameter matched; the saddle arc size is smaller than semi-round; the upper and down saddle pressure blocks arc tank and rock chip are set with at least one layer of film underlay pad. This invention method can maximum reduces measurement error by use of monitor stress to monitor rock wall tangent force.
